Abstract
Components of sense amplifiers may share contacts that couple the components to a global line via a local line. In some examples, the components may be pull-down circuits of a same sense amplifier or pull-down circuits of adjacent sense amplifiers. The shared contact may include a transistor or a resistance between the local line and the global line. In some examples, the global line may be an RNL line. The transistor or resistance may reduce the impact of voltage across the components from affecting the global line and/or reduce the impact of voltage changes on the global line on the individual components.
Claims20
An apparatus, comprising:
- a plurality of sense amplifiers;
- a plurality of shared contacts, wherein individual ones of the plurality of shared contacts are coupled between at least two components of a sense amplifier of the plurality of sense amplifiers or between at least one component of a first sense amplifier of the plurality of sense amplifiers and at least one component of a second sense amplifier of the plurality of sense amplifiers, and wherein the individual ones of the plurality of shared contacts comprise a local line and a resistance;
- and
- a global line coupled to the local line via the resistance of corresponding ones of the plurality of shared contacts, wherein the resistance at least partially isolates the local lines of the individual ones of the plurality of shared contacts from the global line causing each of the plurality of sense amplifiers to be at least partially isolated from one another.
An apparatus comprising:
- a first sense amplifier;
- a first shared contact coupled between at least two components of the first sense amplifier, wherein the first shared contact comprises a local line and a resistance;
- and
- a global line coupled to the local line, wherein the resistance is coupled between the local line and the global line and wherein the resistance at least partially isolates the local line from the global line causing the first shared contact of the first sense amplifier to be at least partially isolated from a second shared contact of a second sense amplifier.
An apparatus comprising:
- a plurality of shared contacts, individual ones of the shared contacts coupled to at least two components and comprising one of a corresponding plurality of local lines and one of a corresponding plurality of resistances;
- and
- a global line coupled to individual ones of the plurality of local lines via individual ones of the plurality of resistances, wherein the global line is configured to provide a common voltage to the plurality of local line and wherein the plurality of resistances at least partially isolates the plurality of local lines from the global line causing the individual ones of the plurality of shared contacts to be at least partially isolated from one another.
